I am not sure if this issue is for views_customfield or faceted_search so I am posting to both.
I am using views_customfield module and faceted_search module.
I have a main view that works with faceted_search to display results of a particular node type.
In that main view I am using a field from views_customfield module.
The field is Customfield: PHP Code.
In that field I am using the Drupal function "views_embed_view" to embed a view within a view for each result.
If I limit the main view to display 5 results per page, in which one of the results displayed on the first page display the embedded view, the results appear fine.
If I increase the main view to display 20 results per page, "Your search yielded no results" appears.
I have been debugging for days, and after commenting every single function in faceted_search.module and faceted_search_ui.module I determined that the difference when viewing 5 results vs 20 results is that:
5 results: in theme_faceted_search_ui_stage_result() function, $pager_total_items[0] == 5
20 results: in theme_faceted_search_ui_stage_result() function, $pager_total_items[0] == 0 <-- this should be 20?
Again, I'm not sure where the issue lies, but I will continue debugging to learn more. For now, I am posting about this issue in case I do discover a bug or a misconfiguration so that if anyone else has a similar issue, they can potentially find a resolution as well.

I believe this may be related to faceted_search because when viewing the Views Preview, 20 or 40+ results per page appear fine, however, when viewing in combination with faceted_search results, 5 results per page appears fine, but 20 or 40+ results per page yields No results.
I discovered in sites/all/modules/views/includes/view.inc:
In class view extends views_db_object { }
In function _build($key) { }
line $pager_total_items[$this->pager['element']] = $this->total_rows;
The first/main view calculates the correct 'total' results that should be displayed on the main faceted_search results page.
The view within a view with views_customfield, for each view that is created, affects this value, depending on how many results there are.
I discovered that on my results page when only displaying 5 results per page, since the last result's view within a view does have results of its own, the results are ultimately displayed, views results and views within a view results.
If I changed to 4 results per page, I would have discovered that there were no results, because the 4th result's view within a view has 0 results.
Therefore, I must learn a workaround so that each view within a view result does not affect the main/initial/first/primary view's results, and therefore affect ultimately displaying them or not. Is anyone able to help me discover a solution for this issue?

Specific to this module, theme_facted_search_ui_stage_results() function can't rely on if ($pager_total_items[0] > 0) { } in the case that Views Custom Fields embeds a view within a view. How can I detect only the main view's pager_total_items[0] value?

A work-around that seems to work for me:
Instead of relying on $pager_total_items[0] for the number of results, since the view within a view makes this value useless,
I modified a couple functions to pass on the correct results.
function faceted_search_ui_stage_results($env_id, $text = '') {
// If the menu system has splitted the search text because of slashes, glue it back.
if (func_num_args() > 2) {
$args = func_get_args();
$text .= '/'. implode('/', array_slice($args, 2));
}
$env = faceted_search_env_load($env_id);
// Initialize the current search.
$env->prepare($text);
$env->ui_state['stage'] = 'results';
if ($text) {
// Log the search text.
$path = faceted_search_ui_build_path($env, $env->ui_state, $text);
watchdog('faceted_search', '%text.', array('%text' => $text), WATCHDOG_NOTICE, l(t('results'), $path));
}
faceted_search_ui_add_robots_directive($env);
faceted_search_ui_add_css();
// Collect the search results.
$env->execute();
$results_num = $env->_results_count;
$style = faceted_search_ui_get_style($env);
if (method_exists($style, 'format_results')) {
$results = $style->format_results($env);
}
faceted_search_ui_set_title($env);
$content = theme('faceted_search_ui_stage_results', $results, $style, $results_num);
return theme('faceted_search_ui_page', $env, $content);
}
function theme_faceted_search_ui_stage_results($results, $style, $results_num) {
global $pager_total, $pager_total_items, $pager_page_array;
//if ($pager_total_items[0] > 0) {
if ($results_num > 0) {
$limit = $style->get_limit();
$from = $pager_page_array[0] * $limit + 1;
$to = min(($pager_page_array[0] + 1) * $limit, $pager_total_items[0]);
$total = $pager_total_items[0];
if ($total == 1) {
$numbering = t('1 result');
}
elseif ($from == $to) {
$numbering = t('Result @to of @total', array('@to' => $to, '@total' => $total));
}
elseif ($total <= $limit) {
$numbering = t('@total results', array('@total' => $total));
}
else {
$numbering = t('Results @from - @to of @total', array('@from' => $from, '@to' => $to, '@total' => $total));
}
$numbering = '<div class="faceted-search-numbering">'. $numbering .'</div>';
return $numbering . theme('box', t('Results'), $results);
}
else {
return theme('box', t('Your search yielded no results'), search_help('search#noresults', ''));
}
